HP Virtual Connect Fibre Channel Networking Scenarios Cookbook

In the portWwn of device(s) connected entry, more than one HBA appears. This indicates a successful
implementation of VC-FC. On the enclosure, two server blade HBAs are installed and powered on, and either an
HBA driver is loaded or the HBA BIOS utility is active.
The third WWN on the port is the VC module (currently, all VC-FC modules use the 20:00…range).
Recommendations
When VC-FC 8Gb 20-port module or VC FlexFabric 10Gb/24-port module Fibre Channel uplink ports are configured to
operate at 8Gb speed, and are connecting to HP B-series Fibre Channel SAN switches, the minimum supported
version of the Brocade FOS is v6.4.x.
In addition, “FillWord” on those switch ports must be configured with option Mode 3 to prevent connectivity issues
at 8Gb speed.
On HP B-series FC switches, use the portCfgFillWord (portCfgFillWord <port#> <Mode>) command to configure
this setting:
Mode
Link Init/Fill Word
Mode 0
IDLE / IDLE
Mode 1
ARBF / ARBF
Mode 2
IDLE / ARBF
Mode 3
If ARBF / ARBF fails, use IDLE / ARBF
Modes 2 and 3 are compliant with FC-FS-3 specifications (standards specify the IDLE/ARBG behavior of Mode 2,
which is used by Mode 3 if ARBF/ARBFfails after 3 attempts).
For most environments, Brocade recommends using Mode 3 because it provides more flexibility and compatibility
with a wide range of devices. If the default setting or Mode 3 does not work with a particular device, contact your
switch vendor for further assistance.
